How do you make producing a habit?

As with any habit, there's no silver bullet. You just have to make a concerted effort to produce something, however small, every day. For example, you could force yourself to comment on a Hacker News post every day, or write 100 words the second you get up in the morning, etc.

The second thing is to just produce things that you're passionate about, not what you think other people will enjoy. Producing work is inherently a personal endeavor; writing about something you hate is a surefire way to kill a habit before it even starts.

Creating for its own sake runs the risk of burning you out. It is important to have the skills to bring an idea to fruition. Selecting the right idea that fits with your goals is equally important if not more important. Polishing a MVP into presentable finished product is another area where people fail.
